UNITED STATES BENjIAMIN ROBERTS, OF INDIANAPOLIS, INDIANA.

SMOKE-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 360,052, dated March 29, 1887.

Application filed November 2, 1886. Serial No. 217,773. (No model.)

To (6 whom it may concern:

Be it known that I, BENJAMIN ROBERTS, of the city of Indianapolis, county of Marion, and State of Indiana, havein vented certain new and useful Improvements in Smoke-Condensers,of which the following is a specification.-

The object of my said invention is to provide an improved means whereby the smoke from a furnace may be condensed and carried away by means of water, instead of being discharged into the air, and thus not only free the atmosphere from impurities and obviate the danger ofsetting property on fire by sparks from smoke-stacks, but also avoid the expense of building smokestacks, all as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof and on which similar letters of reference indicate similar parts, Figure 1 is a front elevation of a battery of steanrboilers and accompanying furnaces provided with my said invention; Fig. 2, a central vertical section through said invention, and extending to and including one of the boilers on the dotted line 2 2 in Fig. 3, on an enlarged scale, and Fig. 3 a horizontal sectional view, looking upwardly from the dot ted line 3 8 in Fig. 2.

In said drawings, the portions marked A represent the ordinary boilers and their furnaces; B, the breeching into which the products of combustion from the furnaces areiminediately discharged; 0, a fan for furnishing a draft to said furnaces D, the main structure of my condenser, and E a supply pipe by which water is conducted thereto.

The furnaces and boilers A are or may be of any ordinary or desired form, and need no special description.

may be driven in any desired manner, although I prefer to drive it bya small independent engine connected by a steam-pipe to the boilers. (Not shown.) I

The casing D to the condenser is preferably a cylindrical sheet-metal structure, as shown, although it may, of course,.be formed of masonry or in any of many other ways. Near its upper end a circular pipe, I), should be placed, connected with the water-supply pipe, and provided with numerous o1'itices,as shown. These orifices I prefer to make at an angle of about sixty degrees, so that the streams of water therefrom shall arch over and fall down toward the center. To a central pipe, D", is connected a revolving globe, D, also having numerous orifices,through which small streams or sprays of water will pass. Rigidly secured to this globe and extending up into the pipe D is a screw, by which the rotary motion is imparted thereto by the water coming through said pipe, and thus the streams of water from the orifices in the globe are thrown out by centrifugal force and serve to dampen everything which enters the condenser. These several streams of water also serve to some extent to form a vacuum in the condenser, and thus the smoke from the breeching will enter it freely, where, by commingling with the water, the gases are purified and the solids are wet and washed down to the bottom of the condenser, whence they run off with the water and are discharged into a sewer or other suitable place. In one side I prefer to place a door or window, D", in which a glass pane (shown as protected by an outer shield of sheet metal) is placed,so that both access may be had to the device and the interior observed when it is closed and in operation.

The supply-pipe E is simply an ordinary pipe by which the necessary supply of water is conducted into the condenser, and may or may not be the same pipe by which water is supplied to the boilers.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is'- 1. The combination, with a furnace, of a condenser, a conduit or breeching leading from said furnace to said condenser, a suction-fan or conduit leading from said furnace to said condenser, a fan in said breeching, and a I 5 damper having an attachment which serves as a continuation of the rear wall of said fan, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis. Indiana, this 20 23d day of October, A. D. 1886.
